I want to make an application like this
Https://[login to view URL]
Slide on the locked screen to reward (ERC_20 Token)
Advertising should be done on the lock screen.
Also, you should be able to easily register various ERC-20s in the backend and register advertisements.
It works just like the example app.
However, the reward is the advertiser's Erc-20 token.
If you can speak Korean, it's good
